Reader requested before image data and logger configured for after images only.
During a CDC session, the log reader requested before images of data from the PowerExchange Logger for Linux, UNIX, and Windows log files. However, the log files do not contain before images because the PowerExchange Logger CAPT_IMAGE parameter is set to AI to store after images only. This error occurs if the PowerExchange Logger image type and the log reader image type are not compatible at the reader restart point.
The CDC session ends.
Set the
Image Type
connection attribute for the CDC session to
AI
for after images only, or set the PowerExchange Logger CAPT_IMAGE parameter to
BA
to store both before images and after images in the log files.
